Recently, the improvement of ride comfort is essential for vehicle designs to add commodity value. A technique to well predict the ride comfort for vehicle passengers is strongly required from the above viewpoint. Vibration comfort such as fatigue and motion sickness are essential elements of ride comfort. It is known experimentally that the ride comfort is influenced by dynamic characteristics of the passenger in the lateral and roll direction at low-frequencies. This paper investigates the modeling of a seated human body by MBD approach for the basis of comfort evaluation. For that, we aim to reproduce the response of the human body in the lateral and roll direction simultaneously.
